Work in progress for a workbench

While waiting for the garage to be available I have started designing a workbench.

Top is Paulk Workbench inspired. A torsion box bottom with casters to make it mobile. Cabinets with drawers in between. The table saw will built into the bench.

Moved at work

We shuffled placements at work. I now work a few meters to the right with a “stunning” view of Bergsgatan.

Sanded center speaker enclosure flat with big sanding pad

My angled cuts were not perfect and there was gaps when laying the baffle on it. I glued a bunch of sand papers to a piece of hard board to have a large abrasive pad that lay flat on my table.

I then pushed the enclosure over it until the edges lined up.

I recut the baffle and routed out the insets for the speakers. I also recut the pieces for the sides as I wanted to make the enclosure deeper. The box is partly glued up now. I keep my glue in a used mustard bottle.

Glued box with baffle in front

This is how it will look.

I also remembered that the tweeter needs a separate enclosure and made a little round box to be mounted behind the tweeter. I should have used the router for this but it was tucked away so I used a couple of holesaws instead. The center hole will be used for the leads and then filled with hotglue.

Surround speakers finished

I have finished the surround speakers.

Wiring thick cables of many thin strands together is a bit tricky. Here’s a neat trick I did to not lose my mind while burning my fingers off.

Strip a mains cable and use a strand to wire wrap the speaker cables together

Use another strand to wire wrap the cables to a terminal

The sound have not changed much to the old ones. They are one speaker less and about 2/3 of the size. The sound is not as deep but given that they are going to play the surround channels they are well up to the task.

I tried playing music at full range with them and they sound a bit thin but still lots of detail.

They measure 200mm * 300mm * 90mm
